Three elements \( X, Y \) and \( Z \) are in the \( 3^{\text {rd }} \) period of the
\( \mathrm{P} \) periodic table. The oxides of \( \mathrm{X}, \mathrm{Y} \) and \( \mathrm{Z} \), respectively,

WV are basic, amphoteric and acidic. The correct order of the atomic numbers of \( \mathrm{X}, \mathrm{Y} \) and \( \mathrm{Z} \) is
[JEE Main-2020 (September)]
(1) \( \mathrm{X}\mathrm{Z}\mathrm{Y} \)
(2) \( \mathrm{Y}\mathrm{X}\mathrm{Z} \)
(3) \( \mathrm{Z}\mathrm{Y}\mathrm{X} \)
(4) \( XYZ \)
